My fallback is always a ketogenic diet (high fat - 80%, but no extra omega 6s, moderate protein - 15%, low carb - 5% from leafy dark green vegetables), combined with intermediate fasting. And occasionally total fasting for more than a day. Except for emergency situations this can help often more than any medicine or procedure. Also, I know you didn't ask, and I know that there are a few decent doctors out there, but in general asking a doctor for diet advice, when his business model depends on return visits, is a little like asking a wolf for design assistance when building your hen house.
